Index plays an essential role in modern database engines to accelerate the query
processing. The new paradigm of" learned index" has significantly changed the way of …

Non-Volatile Memory (NVM), which provides relatively fast and byte-addressable
persistence, is now commercially available. However, we cannot equate a real NVM with a …

Key-value stores (KVSs) have found wide application in modern software systems. For
persistence, their data resides in slow secondary storage, which requires KVSs to employ …

Recently, non-volatile memory (NVM) technology has revolutionized the landscape of
memory systems. With many advantages, such as non volatility and near zero standby …

We present a comprehensive and in-depth study of Intel Optane DC persistent memory
(DCPMM). Our focus is on exploring the internal design of Optane's on-DIMM read-write …

Due to the latency difference between DRAM and non-volatile main memory (NVMM) and
the limited capacity of DRAM, incoming writes are often stalled in LSM tree-based key-value …

The recently released persistent memory (PM) offers high performance, persistence, and is
cheaper than DRAM. This opens up new possibilities for indexes that operate and persist …

Non-Volatile Memory (NVM) has emerged as an alternative to next-generation main
memories. Although many tree indices have been proposed for NVM, they generally use B+ …

We present Nap, a black-box approach that converts concurrent persistent memory (PM)
indexes into NUMA-aware counterparts. Based on the observation that real-world workloads …

The emerging trend of memory disaggregation where CPU and memory are physically
separated from each other and are connected via ultra-fast networking, eg, over RDMA …
